around 3 days after my period me and my boyfriend had very rough sex, in the span of three hours we did it twice and each time lasted about 30-40 minutes, we did it again the following week very quick, all three times he had pre cum but pulled out, im not on birth control and we didn’t use a condom as he pulled out all three times. i think im pregnant though, i took one test and it came out negative. my lower stomach hurts, my sides, my ribs, my pelvic area (im a girl but just the bones near my thighs) i feel bloated, dizzy and tired. im really scared. do you think im pregnant?
